Worked example

Inputs

Queued data
1000000 bytes
Drain rate
100000000 bit/s
Target queue delay
0.005 s

Expected results

Queue drain delay
0.08 s
Bytes at target delay
62500 bytes
Excess queue bytes
937500 bytes

How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "queued": 1000000,
  "rate": 100000000,
  "target": 0.005
}

Accuracy and scope

FIFO fluid queue at fixed drain rate; no prioritization or active queue management is simulated. Simplified analytical model; not a design recommendation or safety certification.
